5 Claims. 1

This invention is an improvement upon my United States Letters PatentNo. 2,018,721, granted October 29, 1935, for improvements in chairshaving flexibly supported seats.

This invention particularly proposes a new system, or arrangement forobtainin superior resiliency, which may be used in numerous articlesanddevices, such as automobile and other seats, bed springs, chairs, andthe like.

It is proposed to characterize the new system, or arrangement by thefact that it includes a plurality of spring bars resiliently supportedand adapted to cooperate with compressed air or pneumatic resilient orcushioning devices. It is contemplated to support the spring bars uponcoiled springs. Seating or supporting material may readily be mountedacross the spring bars. This seatingorsupporting material may be in thenature of slats, woven straw, and other covering materials andsubstances.

This invention also relates to a resilient unit forbed springs, chairs,and other articles.

It is proposed to so construct the new resilient unit that it imparts acertain resilient action to the bed spring or chair or other articletowhich it is applied. It is proposed that the resilient' action beinitially exceptionally soft, and after a certain degree of depression,it becomes relatively firm. With this arrangement when a bed spring,or'chair or other article to which the invention is applied is manuallyfelt by pressing down with the hands it will feel very soft. However,when a heavy load is placed on the bed spring or chair or other article,as for example when a person lies or sits on the article, the firmsupport of the resilient unit will come intoplay for properly supportingthe person. The important advantage of the new construction resides inthe fact that because of the initial softness of the resilient supportit will give the impression that the resilient unit is exceptionallyresilient and comfortable.

It is also proposed that a group of resilient units be used in each bedspring or chair, preferably in the corners thereof. It is contemplatedto mount a spring bar top across the groups of resilient-units. Thisspring bar top may include a plurality of spring bars upon which aperson mayrest, or upon which suitable upholstery or other seatingor'supporting members maybe applied.

Because the spring bar top is supported at the cornersthere issufiicientxroom at the center for a pneumatic. (compressed air) orhydraulic pad to be applied to supplement the supporting action of theresilient units.

Another object of this invention is the construction of a device asdescribed which is simple and durable and which may be manufactured andsold at a reasonable cost.

For further comprehension of the invention, and of the objects andadvantages thereof, refer..- ence will be had to the followingdescription and accompanyin drawings, and to the appended claims inwhich the various novel features of the invention are more particularlyset forth...

In the accompanying drawings forming a material part of this disclosure:

Fig. 2 is a fragmentary enlarged vertical sectional view taken on theline .2-2 of Fig. 1.

Fig. 3 is a fragmentary enlarged plan-view of a corner of the bed springshown in Figs. 1 and 2, but-illustrated with the spring bar top removedso that more parts are discernible.

Fig. 5 is a plan view of the chair shown in Fig.4.

Fig. 6 is a plan view of a bed spring, .or seat embodying the featuresof, this invention.

Fig. 7 is a sectional view taken on the line 1--1 of Fig. 6.

The new and improved resilient unit, in ac-.- cordance with that form ofthe inventionillustrated in Figs. 1 to 3, is applied to a bed 10. Thisbed may be of any design and construction. It may be a singl or doublesized bed. The bed 10 includes a headboard section II, a footboardsection l2, and side rails l4. The space between the side rails 14 isdivided by a longitudinal par..- tition l5 and a transverse partition l6into four equal sections. Spring. support boards l8 are mounted acrosseach of these sections: for sup+ porting a bed spring.

One of the sections referred to in the previous paragraph is illustratedprovided with a bed spring in accordance with this invention. This bedspring includes a bottom support frame 20 rested upon the support bars18. The support frame 20 is rectangular. At each of the corners it isprovided with a support lug 2| for a resilient unit 41. Each resilientunit includes a flat plate or support base 24 attached to a support lug2| with fastening elements or welding. The support base His providedwith a pair of .side arms25. for supporting a lever 26 spaceddron;

the base 24. The lever 26 is pivotally supported on the side arm 25 witha pintle rod 21. A tension spring 29 is connected between the rear endof the lever 26 and the rear end of the base 24 and is for the purposeof urging the front end of the lever 26 upwards.

The spring 29 is associated with adjusting means by which its tensionmay be controlled. This adjusting means includes a member 30 attached toone end of the spring 29. A screw 3| which is threadedly engaged throughan angularly down turned portion 32 formed upon the rear end of the base24, and rotatively connects with the member 38. The screw 3| has a head33 by which it may be easily turned. It is provided with a lock nut 34by which it may be locked in adjusted positions. The top end of thespring 29 is connected with an angularly downturned portion 35 formedupon the rear end of the lever 26. When the nut 34 is loosened the screw3| may be turned for controlling the tension of the spring 29.

The lever 26 is limited to pivot upwards to a substantially horizontalposition. It is limited by a pair of side arms 38 which are rigidlyconnected at their bottom ends with the support base 24, preferably bywelding. Intermediate of their ends the side arms 38 are rigidlyconnected with the side arms 25 by rivets 39 or other fastening members.The top ends of the side arms 38 are provided with inturned lug portions40 which extend over the top face of the lever 26 to the front of thepintle rod 21 for limiting upward pivoting of the front end of the lever26.

A stiff compression spring 42 is mounted upon the base 24 and extendsupwards to a point above the front end of the lever 26. Moreparticularly, the lever 26 is provided with an opening 43 through whichthe compression spring 42 passes. A tranverse member 44 for supporting aspring bar top 46 is mounted on the compression spring 42, whereby saidcompression spring 42 will support a load on said spring bar top 46 upto a certain amount and then said member 44 will engage the lever 26 forpivoting the front end of the lever 26 downwards so that the tensionspring 29 supports some of the load.

The spring bar top 46 is mounted across and supported by the resilientunits 41. These resilient units are generally indicated by the referencenumerals 47. The spring bar top'46 comprises longitudinal support strips48 rigidly connected with and supporting a plurality of closely spacedtransverse spring bars 49. The transverse members 44 extend across andare supported by two of the resilient units 41. The longitudinal strips48 extend across and are supported by at least two of the transversemembers 44. A mat-- tress may be placed directly upon the spring bar top46.

The spring bar top 46 is also shown supported by a pneumatic (air) orhydraulic pad 50. This pad has an inlet valve through which it may beinflated or filled with hydraulic fluid. The pad 50 is supported on atransverse board 52 which is supported by feet 53 rested upon the frame20.

The operation of the resilient units 41 may also be understood by notingthat when a load is initially placed on the spring bar top 46 thecompression springs 42 will support the load and will be compressedunder the load. After a certain amount of compression of the springs 42,the transverse members 44 will engage the front ends of the levers 26,causing the levers to pivot and stretching the springs 29 so that thesprings 29 now assist in supporting the load. Because the levers 26 havea certain mechanical advantage, the springs 29 will function asrelatively stiff or firm supporting means in relation to the supportingaction of the springs 42. The degree of resiliency of the springs 29 maybe varied by the adjustment screws 3|. After the transverse members 44depress the front ends of the levers 26 a predetermined amount thespring bar top 46 will engage the top ends of the side arms 25,preventing any further downward motion of the spring bar top 46.

In Figs. 4 and 5 another embodiment of this invention is disclosed. Thistime the new system or arrangement is applied to a chair 55. Thischair'55 includes a stationary bottom support 56 consisting of a top 51and supporting legs 58. A plurality of springs 59 are stationarilysupported on the top 51 and support a seat 6| for the chair. A seat back62 is rigidly connected with a seat 6|. A rod 64 is pivotally connectedby a pintle 65 with one corner of the top 51. This rod 64 is provided atits outer end with a coiled portion 61 adapted to engage about an eyemember 68 on the support bar 69 of a table 10. This arrangement isparticularly intended for restaurants and other public places where thepublic shifts the chairs to undersirable places from the tables. Withthe new construction it is possible to move the chair 55 only intopositions as limited by the rod 64.

The seat 6| and back 62 may be of wood, or other hard materials. Thesprings 69 are depended upon to provide resiliency for the seat 6| andseat back 62 so as to make the chair comfortable.

In Figs. 6 and 7 another embodiment of the invention is shown. It ishere applied to a bed spring, or foundation for an automobile seat. Thisdevice includes a frame 15 having a bottom flange 16 upon which aplurality of springs 11 are fixedly attached. These springs Tl extendupwards and are fixedly attached to and support a plurality oftransverse spring bars 18. A covering 19 is attached to and mountedacross the spring bars 18. This covering 19 may be in the nature of awire link fabric connected to the spring bar 18 by coil springs. It mayalso comprise other covers of various designs and natures. When amattress is placed upon the cover 19 the article may be used as a springfor a bed. Seat material may be built upon the covering 19 so that thedevice may then comprise an automobile seat, or other seating articles.
